This unique Linux networking tutorial reference provides students with a practical overview and understanding of the implementation of networking protocols in the Linux kernel. By gaining a familiarity with the Linux kernel architecture, students can modify and enhance the functionality of protocol instances.

• General introduction to Linux and the Linux network architecture in particular.

  • Provides students with the foundational knowledge they need to learn about the complex, network subsystem in the Linux kernel.

• Explanation of the networking architecture in the Linux kernel.

  • Gives students the essential components they need to understand the Linux kernel which they can apply to the study of new network functionalities.

• Complete description of the protocols in the Linux kernel.

  • Includes an introduction of the general architecture of communication systems and the functionality of protocols and protocol instances, including the popular TCP/IP and ISO/OSI layering models.

• Implementation techniques of networking protocols.

  • Shows how networking behavior and protocols can be used within the Linux operating system.

• Linux Source Code Browser.

  • Explanation of this browser is provided in the appendix to help students improve navigation through the kernel source code.

Written to give students and professionals the basics required to implement network functionality in the Linux kernel, this book also addresses everyone who wants to deepen their understanding of network specific processes in an operating system. This book introduces the key components and mechanisms of the Linux kernel and the designs of communication systems.

The Linux Networking Architecture is a detailed description of the network subsystem in the newer versions of the Linux kernel. It explains how protocols work and establishes important concepts of the Linux network architecture from device drivers to application interfaces. In addition to central issues such as PPP, IP, firewalls, routing, TCP, NAT, UDP, and sockets, the book discusses more recent protocols and extensions such as PPPoE used in DSL access technologies, the Bluetooth^® driver, and quality-of-service support.

All core protocols of the TCP/IP protocol family are covered, with additional treatment of supplementary protocols such as RSVP, Mobile IP and IP Security.

Each chapter contains:

• A conceptual introduction to the corresponding protocol
• Discussion of how the protocol's functionality is configured and administered
• Explanation of data structures, algorithms, and programming interfaces

Interface design is explained with a view to which design principles to use when protocols should be implemented.

The informational appendix further facilitates working with Linux, for instance, debugging in the Linux kernel.
